Beyoncé can have that effect on people! Jaime King bursts into dance during baby photo shoot with husband Kyle Newman

She has maintained an impressively demure image throughout her pregnancy.

But Jaime King couldn't help but let her playfulness take over as she jiggled about to a Beyoncé hit during a baby photo shoot with her husband Kyle Newman.

The pregnant 34-year-old injected a dose of fun into the shoot, interrupting the couple's sweet and loved-up poses with hilarious impromptu dance moves as Crazy In Love played in the background.

The blonde beauty had her tresses styled in neat curls and her make-up minimally done for what looked to be photo shoot to document her pregnancy.

Jaime wore a basic pink tank and looked utterly demure as the couple prepared to have a few special moments captured.

Beyoncé's dance floor hit Crazy In Love played on as Jaime flashed the camera a cute gaze and moved to the beat.

When it was time for Jaime and Kyle's photos together, the film director wrapped his arms lovingly around his wife.

But as Beyoncé's chorus hit, Jaime broke her pose and let loose, hilariously dancing up a storm.

Her bemused husband shot the camera a deadpan stare as she jiggled out of his arms to the beat.

Kyle tried a couple of his own dance moves, but with significantly less comedic enthusiasm than Jaime.

The Fanboys actress announced her pregnancy in May of this year and has wowed onlookers with her impressive maternity style ever since.

Jaime has looked nothing short of chic on every outing, often opting for a stanard pair of jeans in lieu of traditional maternity wear.

She and Kyle, who are expecting their first child together, have been married since 2007.
